To all whom it may cancer n:

Be it known that I, ARCHIE AITCHISON,

a citizen of the United States, residing at St. Petersburg, in thecounty of Pinellas and v the use of the device when received by acustomer, as a right or left hand sash opener, and it is also essentialthat the members for fastening the device to a window accompany thesame, as they must serve as a keeper for the lever, a journal for itsguide roller, and a support for the spring which tensions said lever.These parts being permanently confined within a casing, but loosetherein, great care and accurate adjustment thereof is necessary whenfastening the device in position for use.

Therefore, to meet these requirements, it is the primary object of thepresent invention to provide a device of this character, wherein thelever, spring and roller can be reversed when the device has beenreceived by a customer or user to permit, at his option, the working ofthe same as a right and left hand window opener. The casing, being ofnovel form, allows the interchanging of the parts with despatch andwithout the aid of the fastenersfor securing the device to a window,thus providing a single article convertible by a user to a dual purpose.

The invention will be particularly explained in the followingdescription.

Reference is to be had in the accompanying drawings forming a part ofthis specification, in which similar characters of reference-indicatecorresponding parts in all the views.

In the accompanying drawing: Figure 1 is a horizontal sectional viewthrough awindow sash and casement showing the operating deviceconstructed in accordance with the invention; by full lines the windowsash is shown closed, and by dotted lines in open position.

Fig. 2 is a similar view of the sash closed with the operating lever andadjunct parts reversed.

Fig. 7 is a perspective view ofthe top or cover section of the casing.

Fig. 8 is a perspective view of the base or bottom section of saidcasing.

In the practical embodiment of the invention, in accordance with theillustrated example, a portion of a casement 10 and. a sash 11 of awindow are shown. The sash is shown in Fig; 1 as hinged to the jamb atthe left hand side, and in Fig. 2 at the right hand side of said jamb ofthe easement in the usual manner. The casement has fitted therein infront of the outwardly swinging sash 11 a screen 12. The screen isprovided in its lower end with a slot- 13 through which the sashoperating device works and freely actuates, as willbe hereinafter fullydescribed- The sash operating device comprises an operating lever 14preferably made from a strip or bar of metal curved edgewise at one endto form-an angularly disposed ter- 'minal portion for pivotal attachmentto the window sash 11. Mounted on the lower end of the sash at anintermediate point thereof is an angle or L-shaped bracket or ear 15;the laterally extending portion of which carries a pivot bolt 16swingingly connecting the curved terminal portion of the lever 14 to thebracket or ear 15. The other end portion of the lever 14 is adapted toslide through the slot 13 in the screen 12 and works within a casingmounted upon the tongues 21 formed and bent from the ends of the base orbottom section 18 of the easing. The casing may be of any suitable orcasement sill 17 as hereinafter fully dedesirable shape, and the top orcover section 19 at its front and back is open to constitute a way forslidably receiving the lever 14 which works within said casing. The cas-:ing is disposed on the easement sill 17 in front of the screen 12, andthe open rear portion of the top or cover section 19 registers with theslot 13in said screen for the free passage of the lever 14 whenswinging'thesash to open or closed position.

Riveted 'or otherwise secured in the base or bottom section 18 arevertically disposed hollow posts or studs 22, which open through saidbase or bottom 18 and are of a lengthy corresponding to the distancebetween the base or bottom section and the top or cover or studs 22which serves casement.

- silient section of the casing. The top or cover sec tion 19 is formedat properly located points with openings or holes 23, registering withthe passages through the ho low posts or studs 22 for accommodatingfasteners to secure 'the casing to the sill of the window The fastenersin this instance are in the form of screws 24, which are passed throughthe openings or holes 23 m the to or cover'section 19 when interlockedw1th the base orbottom section 18, and also passed through the hollowposts or studs 22 and engaged in the sill 17 of the window casing forthe fastening of the easing in place.

Adapted to be journaled in the casing upon either of the hollow posts orstuds 22- is an anti-friction guide roller 25, against which works thelever 14 in its movements. The lever 14 in the free end portlon thereofis formed at intervals with notches 26 for engagement with one of thehollow posts as a keeper for the lever to hold the same in adjustedosition when the sashll has been swung om closed position to therequired open position. The lever 14 carries at its free end a hand knob27 to provide for the ready gripping and operation of said lever.

Within the casing between the base or bottom section 18 and the top orcover section 19 thereof, is adapted to be confined a tension sprmgwhich is made from a single length of wire bent on itself to form areloop aw 28 to straddle one edge of the lever 14, with an ofl set end29 which constitutes astirrup for said lever. Intermediate spacedregistering coils or convolutions 30 v and below the guide roller 25,which is positioned betweenthe coils or convolutions of said spring,while the remaining end portlons 31 of the spring lie crosswise aboveand. below the lever 14 and are engaged against the other hollow post orstud 22, so

that the spring will be tensioned for the jaw 28 to be active upon thelever for maintaming it constantly in position for the as shown areadapted to engage upon either of the hollow posts or studs 22 to lieabove one of the hollow posts or studs 22, when said lever ispositionedas shown in Figs. 1 and v2 of the drawings.- The notches 26 inthe lever 14 are designed to receive the hollow post or stud 22 andserve as the keeper for the lever when the sash is swung open to thedesired adjusted position.

' When the lever 14 is-to be reversed for the right hand or left hand,operation thereof, the top or cover section 19 of the casing is removedfrom its base or bottom section 18, the spring constituting the jaw 28and the roller '25 are detached from one of the hollow posts or studs 22and engaged on 'the other hollow post or stud either at the right orleft hand end of the casing, according to the desired use of the lever14 for the right or left hand opening of the sash of the window. Whenthe parts have been assembled, the top of cover section 19 is engagedwith the base or bottom section 18, whereupon the fasteners 24 arepassed through the open-- ings or holes 23 in said top or cover sectionand the hollow posts or studs 22 on the base or bottom section of thecasing, and engage in the sill 17 of the window casementfor thefastening of the device in place. It is of course understood that inreversing the lever the same is detached from the saslli1 and thereafterproperly engaged therewit -A catch 32 is mounted on the window sill 17and is designed to engageand securely lock the 'lever' 14 when the sash11 is in closed position, as shown in either Fig. 1 or .Fig. 2 of thedrawings, whereby the sash is firmly held closed. The catch 32 may be ofany approved form for engaging and holding the lever 14. p Intheoperation of the device, when the window is in closed position asshown in either Fig. 1 or Fig. 2 of the drawings, and it is desired toopen it, the knob 27 on the lever 14 is grasped by the operator and thepaid lever moved laterally outwardly against e jaw 28, which causes therear edge of said lever to come in contact with the roller 25. Thisengagement, together with the force exerted by the operator on the knob.27, will forcibly push the sash-11 into open position.

by dottedlines in Fig.1 of the drawings, and when it has been disposedat the desired angle, one ofthe notches 26 in said lever will beengagedwith the adjacent hollow post or stud 22, andthe spring bearing uponsaid lever will hold it in locked engagement therewith, thereby firmlyholding the sash in adjusted position where it will remain until thelever 14 is manually released.

It will be clearly obvious that the device when received by a customeror user can be tension of the spring constituting the macaw? readilyandconveniently adjusted at the option of the customer or user for its useeither [as a right or left hand window sash opener.

The parts of the device are of such construction as to permit the easyassemblage thereof by the user and the application to a window, theroller and the spring for coaction with the lever being interchangeableto either of the hollow posts or studs 22 on the base or bottom. section18 of the casing upon the removal of the cover or top section 19 thereoffor reversing the operation of the device to adapt it for opening aright or left hand swinging sash.

The fasteners for securing the casing in place do not serve as a keeperfor the lever nor a journal for the roller and support for the spring,these being the functions of the hollow posts or studs as hereinbeforeset forth.

The fasteners 24 secure the sections of the casing together and alsofasten the casing in place upon a window, as will be obvious.
